Two Florida animals are the American bittern and the Key deer. The bittern is a bird that has a buff and brown colored back that allows it to blend in with the sawgrass of the lakes it lives near. When it feels threatened, the bittern freezes and points its head skyward to resemble a reed. The Key deer is brown in color, lives in the forest, and freezes when it feels threatened.
How do these two animals use similar adaptations in order to survive in their very different environments?

• Both the bittern and the deer use their small size to hide from approaching predators.
• Both animals live in groups and huddle together with their family for protection from predators.
• Both animals use their coloring and lack of big movement to avoid being seen by predators. 
• Both the bittern and the deer use the movement of trees and bushes around them to distract predators.

What is the purpose of the kidneys in the human body?

• Kidneys mix blood and oxygen together
• Kidneys store unwanted fluids until they can be removed

• Kidneys help balance the salts and acids in the body by filtering blood and removing excess water.
